Comments on: Simple Object Pooling in Flash http://jacwright.com/blog/389/simple-object-pooling-in-flash/ Flex, AIR, PHP, etc. Thu, 26 Aug 2010 22:38:43 +0000 hourly 1 http://wordpress.org/?v=3.0.1 By: Jacob Wright http://jacwright.com/blog/389/simple-object-pooling-in-flash/comment-page-1/#comment-9109 Jacob Wright Fri, 12 Mar 2010 19:17:38 +0000 http://jacwright.com/blog/?p=389#comment-9109 I'd heard of Tweensy. Just haven't looked into it. I did now. One difference is that he goes for easier API by using anonymous objects (e.g. {x: 10, y:20}) for the properties of a tween. Though there is pooling that can be turned on, he could take it a step further and pool the objects for tweening. To make a better API and reduce objects even more you could create specific types of property tweens as you need them. MoveTween could have an x and y property on it (and even handle motion blur for you). Alpha tween could just take one number for the alpha and could have logic to set visible to false if alpha reaches 0. Lots of optimizations still to be had. I’d heard of Tweensy.

Shane's got an excellent writeup on different object pooling strategies (w/ source) and their application to Flash. Check it out! http://www.lostinactionscript.com/blog/index.php/2008/10/30/object-pooling-in-as3/ Oh, I thought for sure you’d have seen it.

I'll check it out. Marc: That is the point. Pooling means reusing the objects later. By setting the tween.next to pool and then pool to tween we are storing a chain of objects that can be used later, rather than always creating new objects.

In the put function, don't you want to do pool = tween; that way on the next get, this returned tween will be accessible. Thanks Cool post. In the put function, don’t you want to do

pool = tween;

that way on the next get, this returned tween will be accessible.

Thanks

I'm sure you're familiar with it already, but if not, here's Shane's writeup: http://www.lostinactionscript.com/blog/index.php/2008/08/31/as3-tween-engine-tweensy-preview/. The object pool classes in Tweensy are general purpose and super easy to use outside of his projects.
